Technical Field

[0001] The invention belongs to the technical field of baling machines and relates to an automatic baling machine. Background Art

[0002] In order to achieve environmental protection and improve resource utilization efficiency, waste paper, plastic and other waste products are usually recycled. In this process, in order to optimize transportation and reduce logistics costs, the recyclables usually need to be compressed and packaged to reduce the volume and increase the payload of each transportation.

[0003] For example, a utility model with application number CN201420859970.2 provides an automatic baling machine, including a frame body, a material pressing mechanism, a wire hooking mechanism and a wire twister; both ends of the frame body are penetrated by material pressing cavities, the material pressing mechanism is arranged in the material pressing cavity, the wire hooking mechanism is fixed on one side of the frame body, the wire hooking mechanism is provided with a threading fork that can vertically pass through the material pressing cavity, and threading holes are opened on both sides of the frame body; the wire twister is fixed on the other side of the frame body and covers the threading holes, the wire twister includes a wire cutting mechanism and a wire twisting mechanism, the wire cutting mechanism includes a wire cutting knife and a wire cutting cylinder, the wire twisting mechanism includes a rotatably mounted wire twisting hook and a wire twisting motor, the wire cutting knife and the wire twisting hook are located on the movement path of the wire threading fork.

[0010] In the above-mentioned automatic packaging machine, the thread hooking rod is provided with an inclined surface and a first pulley, the inclined surface is arranged at the end of the thread hooking rod away from the thread hooking driving element, and the first pulley is rotatably connected to the end of the thread hooking rod away from the thread hooking driving element.

[0012] In the above-mentioned automatic baling machine, a limiting clamp is also provided on the other side where the frame body is connected to the mounting frame, and the limiting clamp on the frame body side is aligned with the limiting clamp on the mounting frame side.

[0013] In the above-mentioned automatic packaging machine, it also includes an adjusting nut, and the frame body and the mounting frame are both provided with adjusting holes, and the adjusting nut is connected to the limit clamp in a liftable manner through the adjusting hole.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Compared with conventional balers, this baler has been significantly optimized in design, especially the layout of the entire wire hooking mechanism and the wire twisting mechanism. In conventional balers, the wire hooking rod adopts the form of pushing the wire and needs to be in the press car for a long time. It is easy to cause the press car to retreat due to reasons such as pressure release of the press cylinder, resulting in the displacement and jamming of the wire hooking rod. The wire twisting mechanism and the wire hooking mechanism of this baler are arranged on the same side of the frame body. When twisting the wire, the wire hooking rod has retracted to one side of the mounting frame, reducing the time the wire hooking rod is in the press car, thereby greatly avoiding the damage of the wire hooking rod caused by pressure release of the press cylinder, which not only reduces the maintenance cost caused by mechanical failure, but also improves the overall safety and reliability.

[0021] 2. The design of the inclined surface not only allows the wire to move along the set trajectory through the inclined surface, but also reduces the friction and impact force that may be generated between the two, ensuring the smooth progress of the entire process. Pulling the deviated wire back through the first pulley can reduce the wear on the wire while adjusting its position, thereby extending the service life of the wire.

[0022] 3. The limit clamp can ensure that the wire is fixed within a specific height range, ensure that the wire can contact the inclined surface and be brought to the side of the mounting frame by the hook rod, which provides a guarantee for the subsequent twisting operation and increases the reliability of the baler.

[0023] 4. By rotating the adjusting nut, its height relative to the limit clamp is changed. Since one end of the limit clamp is in contact with the adjusting nut, the rotation range of the limit clamp can be adjusted, thereby adapting to wires of different specifications so that they can all be guided and fixed by the limit clamp and the wire hook rod, thereby improving the flexibility of the baler.

[0024] 5. The first blade adopts an integrated design. Compared with multiple first blades, the motion path and cutting action of a single blade are easier to predict and control, thereby improving the accuracy and consistency of cutting. The first blade with an integrated design can respond to the action instructions of the tangent drive element more quickly, shortening the time cycle from starting to completing cutting. It not only improves work efficiency, but also gains more time for subsequent operations, improving the smoothness of the entire packaging process. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] like Figure 1-Figure 5 As shown, an automatic baling machine includes: a frame body 1, a material pressing mechanism 2, a wire hooking mechanism 3 and a wire twisting mechanism 4.

[0039] The frame body 1 is provided with a material pressing cavity (not shown in the figure), a material feed port 11 communicating with the material pressing cavity is opened on the top of the frame body 1, and the frame body 1 is also provided with a threading hole (not shown in the figure).

[0040] The pressing mechanism 2 includes a pressing trolley 21 and a pressing cylinder 22. The pressing trolley 21 is accommodated in the pressing cavity. The pressing cylinder 22 is disposed on the frame body 1. The pressing cylinder 22 can drive the pressing trolley 21 to move in the pressing cavity.

[0041] The thread hooking mechanism 3 is arranged on the side of the frame body 1, and the thread hooking mechanism 3 includes a mounting frame 31, a thread hooking rod 32 and a thread hooking driving element 33. The number of the thread hooking rods 32 is at least two, the mounting frame 31 is connected to the frame body 1, the thread hooking driving element 33 is connected to the mounting frame 31, the thread hooking rod 32 is slidably connected to the mounting frame 31, the thread hooking rod 32 can be slidably connected to the frame body 1 through the threading hole, one end of the thread hooking rod 32 is connected to the thread hooking driving element 33, and the thread hooking driving element 33 can drive the thread hooking rod 32 to move back and forth into the pressing chamber.

[0042] The wire twisting mechanism 4 and the wire hooking mechanism are arranged on the same side of the frame, and the wire twisting mechanism 4 includes a wire twisting hook 41, a wire twisting driving element 42, a wire cutting knife group 43 and a wire cutting driving element 44. The wire twisting driving element 42 and the wire cutting driving element 44 are both connected to the mounting frame 31, the wire twisting hook 41 is rotatably connected to the mounting frame 31, and the number of the wire twisting hooks 41 is twice the number of the wire hooking rods 32 and are respectively located on both sides of the wire hooking rods 32, the wire twisting driving element 42 can drive the wire twisting hook 41 to rotate relative to the mounting frame 31, the wire cutting knife group 43 is connected to the mounting frame 31 in a liftable manner, the number of the wire cutting knife groups 43 is the same as the number of the wire hooking rods 32, and the wire cutting driving element 44 can drive the wire cutting knife group 43 to rise and fall relative to the mounting frame 31.

[0043] The waste paper or plastic that needs to be packaged is put into the feed port 11, and then the waste paper or plastic that needs to be packaged is put into the feed port 11, and then the waste paper or plastic that needs to be packaged is put into the feed port 11, and then the waste paper or plastic that needs to be packaged is put into the feed port 11, and then the waste paper or plastic that needs to be packaged is put into the feed port 11, and then the waste paper or plastic that needs to be packaged is put into the feed port 11, and then the waste paper or plastic that needs to be packaged is put into the feed port 11, and then the waste paper or plastic that needs to be packaged is slipped down and enters the press chamber, and the press cylinder 22 drives the press chamber 21 to move, compressing the waste paper in the press chamber to reduce its volume, and then the threading drive element drives the wire hooking rod 32 to enter through the threading hole until its tip can touch the iron wire pre-set on one side of the mounting frame 31 and the other side of the frame body 1, and after completing this action, the wire hooking rod 32 continues to return to the initial position along the original path, and at the same time ensures that the iron wires at both ends are smoothly brought back to the side of the mounting frame 31, forming a closed loop surrounding the compressed waste, at this time, the wire twisting drive element 42 drives the wire twisting hooks 41 on both sides of the wire hooking rod 32 to rotate to twist the iron wires on both sides of the wire hooking rod 32, and after the twisting is completed, the wire cutting drive element 44 drives the wire cutting knife group 43 to cut the iron wire, and finally, the wire twisting hook 41 rotates to twist the iron wire after the wire cutting is completed, and at this time, the compression and packaging of the waste is completed.

[0044] In the present embodiment, compared with the conventional baling machine, the design of the baling machine is significantly optimized, especially the layout of the entire wire hooking mechanism 3 and the wire twisting mechanism 4. In the conventional baling machine, the wire hooking rod 32 adopts the form of pushing the wire and needs to be in the material pressing cart 21 for a long time. It is easy for the material pressing cart 21 to retreat due to the pressure release of the material pressing cylinder 22 and other reasons, thereby causing the wire hooking rod 32 to deviate and get stuck. The wire twisting mechanism 4 and the wire hooking mechanism 3 of the baling machine are arranged on the same side of the frame body 1. When twisting the wire, the wire hooking rod 32 has retracted to one side of the mounting frame 31, reducing the time that the wire hooking rod 32 is in the material pressing cart 21, thereby greatly avoiding the damage of the wire hooking rod 32 caused by the pressure release of the material pressing cylinder 22, which not only reduces the maintenance cost caused by mechanical failure, but also improves the overall safety and reliability.

[0045] like Figure 1-Figure 5 As shown, based on the above embodiment, the thread hooking rod 32 is provided with an inclined surface 321 and a first pulley 322, the inclined surface 321 is provided at one end of the thread hooking rod 32 away from the thread hooking driving element 33, and the first pulley 322 is rotatably connected to the end of the thread hooking rod 32 away from the thread hooking driving element 33.

[0046] Specifically, when the wire hooking rod 32 approaches the iron wire pre-set on the frame body 1, the inclined surface 321 first contacts the iron wire, thereby shifting the iron wire upward or downward along the inclined surface 321. When the wire hooking rod 32 returns along the original path, the first pulley 322 contacts the iron wire, thereby driving the iron wire back to the side of the mounting frame 31.

[0047] In this embodiment, the design of the inclined surface 321 not only allows the iron wire to move along a set trajectory through the inclined surface 321, but also reduces the friction and impact force that may be generated between the two, thereby ensuring the smooth progress of the entire process. Pulling the offset iron wire back through the first pulley 322 can reduce the wear on the iron wire while adjusting its position, thereby extending the service life of the iron wire.

[0048] like Figure 1-Figure 5 As shown, on the basis of the above embodiment, it also includes a limit clamp 34, which is swingably connected to the mounting frame 31, the number of the limit clamps 34 is the same as the number of the wire hooks 41, and the limit clamp 34 and the wire hooking rod 32 are on the same horizontal line and are respectively located on both sides of the wire hooking rod 32.

[0049] Specifically, both sides of each hooking rod 32 are provided with limiting clamps 34. When the wire is pre-set on the frame body 1, the limiting clamps 34 limit its height, so that when the hooking rod 32 moves, the inclined surface 321 can contact the wire.

[0050] In this embodiment, the limit clamp 34 can ensure that the iron wire is fixed within a specific height range, ensure that the iron wire can contact the inclined surface 321 and be brought to the side of the mounting frame 31 by the wire hook rod 32, which provides a guarantee for subsequent wire twisting operations and increases the reliability of the baling machine.

[0051] like Figure 1-Figure 5 As shown, based on the above embodiment, a limiting clip 34 is also provided on the other side where the rack body 1 is connected to the mounting bracket 31 , and the limiting clip 34 on the rack body 1 side is aligned with the limiting clip 34 on the mounting bracket 31 side.

[0052] In this embodiment, a limit clamp 34 is also provided on the frame body 1 on the other side, and the limit clamp 34 on the frame body 1 side is aligned with the limit clamp 34 on the mounting frame 31 side. While ensuring that the height of the iron wire on the frame body 1 side can be contacted by the wire hooking rod 32, the limit clamp 34 on the frame body 1 side can also serve as a support point for the iron wire, ensuring that only the part of the iron wire in contact with the wire hooking rod 32 is brought to the mounting frame 31 side.

[0053] like Figure 1-Figure 5 As shown, based on the above embodiment, it also includes an adjusting nut (not shown in the figure), the frame body 1 and the mounting frame 31 are both provided with an adjusting hole 311, and the adjusting nut is connected to the limit clamp 34 in a liftable manner through the adjusting hole 311.

[0054] Specifically, the adjustment hole 311 is set as a threaded hole. When the adjustment nut is rotated, the adjustment nut can be raised or lowered relative to the limit clamp 34. When the iron wire contacts the inclined surface 321, the height of the iron wire changes, and the limit clamp 34 can swing accordingly with the change of the height of the iron wire. One end of the limit clamp 34 can contact the adjustment nut during the swinging process.

[0055] In this embodiment, the height of the limit clamp 34 is changed by rotating the adjusting nut. Since one end of the limit clamp 34 is in contact with the adjusting nut, the rotation range of the limit clamp 34 can be adjusted, thereby adapting to iron wires of different specifications so that they can all be guided and fixed by the limit clamp 34 and the wire hook rod 32, thereby improving the flexibility of the baler.

[0056] like Figure 1-Figure 5 As shown, based on the above embodiment, the tangent knife group 43 includes a first blade 431 and a second blade 432, the first blade 431 is connected to the tangent drive element 44, the second blade 432 is connected to the mounting frame 31, and the tangent drive element 44 can drive the first blade 431 to move relative to the second blade 432.

[0057] In this embodiment, the first blade 431 and the second blade 432 are used to cut the portion after the twisting is completed. The second blade 432 is fixed to the mounting frame 31. The wire cutting drive element 44 pushes the first blade 431 to move toward the second blade 432, thereby cutting the wire between the first blade 431 and the second blade 432. Each group of hooking rods 32 corresponds to a group of first blades 431 and second blades 432, so that the wire can be accurately cut after the twisting is completed.

[0058] like Figure 1-Figure 5 As shown, based on the above embodiment, the number of the second blades 432 is the same as the number of the thread hooking rods 32, and the number of the first blade 431 is one.

[0059] In this embodiment, the first blade 431 adopts an integrated design. Compared with multiple first blades 431, the movement path and cutting action of a single blade are easier to predict and control, thereby improving the accuracy and consistency of cutting. The first blade 431 with an integrated design can respond to the action instructions of the tangent drive element 44 more quickly, shortening the time period from starting to completing cutting, which not only improves work efficiency, but also gains more time for subsequent operations, thereby improving the smoothness of the entire packaging process.

[0060] like Figure 1-Figure 5 As shown, on the basis of the above embodiment, the limiting clamp 34 is further provided with a second pulley 341 , and the second pulley 341 is rotatably connected to the middle part of the limiting clamp 34 .

[0061] In this embodiment, the iron wire is always in contact with the second pulley 341. As the main support point of the iron wire, the second pulley 341 plays a guiding role when the wire hook rod 32 pulls the iron wire, ensuring that the iron wire can move smoothly along the surface of the second pulley 341 without causing surface damage due to direct friction. At the same time, the second pulley 341 cooperates with the first pulley 322 to keep the iron wire in a suitable tension state at all times.

[0062] like Figure 1-Figure 5 As shown, on the basis of the above embodiment, it also includes a pushing block 5, which is slidably connected to the mounting frame 31, one end of each of the thread hooking rods 32 is connected to the pushing block 5, and the thread hooking driving element 33 can drive the pushing block 5 to slide relative to the mounting frame 31.

[0063] In this embodiment, one end of the thread hooking rod 32 is connected to the pushing block 5, and the pushing block 5 can drive multiple thread hooking rods 32 to move synchronously at the same time, reducing the error caused by the individual thread hooking rods 32 deviating from the predetermined track. At the same time, compared with controlling multiple thread hooking rods 32 separately, this method not only reduces the complexity of control, but also improves the reliability and maintenance convenience of the system.

[0064] like Figure 1-Figure 5 As shown, on the basis of the above embodiment, it also includes a transmission chain (not shown in the figure), and the mounting frame 31 is also provided with a rotating part 312, and the two sides of the transmission chain are respectively engaged with the rotating part 312 and the output shaft of the hooking driving element 33, and the pushing block 5 is connected to one section of the transmission chain.

[0065] Specifically, since both sides of the transmission chain are respectively engaged with the rotating part 312 and the output shaft of the hooking driving element 33, when the output shaft rotates, the transmission chain will rotate with the rotation of the output shaft, and the rotating part 312 of the mounting frame 31 can rotate accordingly, thereby supporting the position of the transmission chain.

[0066] In this embodiment, since the transmission chain is connected to the output shaft of the wire hooking driving element 33 in a meshing form, the transmission chain can respond to the motion signal of the wire hooking driving element 33 in a timely manner and transmit it to the pushing block 5 connected thereto, thereby driving the pushing block 5 to move back and forth, ensuring smooth and efficient operation of the entire system.
